"Confirmed?" Liang Yi did not expect that things would go so smoothly. This was one of the reasons. The more important point was that he did not expect that Su Ziqing was really the murderer. Liang Yi had been engaged in criminal investigation for so many years, and this was the first time that he felt so relaxed.

Was it a mistake to solve the case?

This newcomer Xiao Liu, although he has worked in the Haigang City Police Department for three or four years, is still a doctor of medicine, has a relatively introverted personality, doesn't talk much, and is relatively shy. He has always been Han Qi's assistant.

Is there a flaw in the testing procedure that results in inaccurate test results?

The murderer of Qin Peng did not leave any fingerprints, and the ground was treated with disinfectant. How could he be so careless?

"I'm very sure Officer Liang! You provided me with a wooden comb and a toothbrush. After collecting the DNA, it completely belongs to the same person as the hair in the transparent plastic bag. The DNA degree coincidence rate reaches 99.8%.

It's certain." Xiao Liu was eager to express himself. This was the first time that Xiao Liu independently took on the key tasks of forensic testing after a murder occurred. He solved the case so easily, and Xiao Liu also felt very accomplished.

"Liang Tou, where is Su Ziqing now? You can call her for questioning. Is there any alibi and does she qualify for murder? You will know after just asking."

When Xiao Liu listened to Liang Yi's call, he didn't say anything for a long time, and then he simply made a very conventional suggestion.

Liang Yi was a little stunned. What Xiao Liu said was very reasonable and was a formal procedure. "You are right! Don't tell anyone in the bureau about Xiao Liu's test results for the time being! There may be something wrong with the physical evidence samples collected. I'll go first."

Contact Su Ziqing. Su Ziqing has been cooperating very closely with our police. He has been an informant for nearly seven years. If he is said to have committed a murder, I really don’t believe it."

Su Ziqing is a police informant?

Although Xiao Liu is not very proficient in criminal investigation, and he doesn't know much about undercover agents, the police informant Xiao Liu is very clear. There are many people who will provide the police with some very valuable information, which is very useful for the police in handling cases.

, is very helpful in catching suspects, and such people often become informants.

"Liang Tou, then I can only keep it secret for the time being! Logically speaking, I must report to the superior department no later than two hours after the test results come out! Please understand." Forensic doctor Xiao Liu did not dare to break the rules.

"Two hours is enough." Liang Yi hurriedly hung up the phone. It makes no sense for him to contact Su Ziqing now. If Su Ziqing really killed Qin Peng, according to my very anti-investigation ability, Su Ziqing's thinking and habits of the police in handling cases

I know all the routines very well, and I can tell them even when I'm talking in my sleep.

If Su Ziqing really killed Qin Peng, how could he take out his DNA sample so easily?

Besides, it makes no sense for Su Ziqing to kill Qin Peng.

Dial Su Ziqing's phone number.

The phone rang with a busy signal, and Liang Yi let out a long sigh of relief. Fortunately, Su Ziqing had not turned off the phone and could be contacted. After reading the conversation in Fang Library, Liang Yi's tone was a little too strong, which also put a lot of pressure on Su Ziqing.

The phone kept ringing for more than thirty seconds, but Su Ziqing did not answer the call.

Liang Yi continued to call.

When Su Ziqing saw Liang Yi's call, she really didn't want to answer it. It must be up to no good. At this time, the results of the DNA comparison test were just coming out.

It's definitely not good for Liang Yi to call at this time. It seems that Liang Yi must have found key evidence at Qin Peng's house.

Su Ziqing wanted to leave Haigang City and go to the ancient city first.

After visiting the ancient city, the transportation in the ancient city is well developed, and it will be easier to go to other places, other provinces and cities.

Su Ziqing didn't dare to go to a train station, let alone take a plane, or even a high-speed rail station. These are places that require a high degree of real-name control.

The current bus station in Haigang City also requires real-name tickets to be purchased. Su Ziqing stood outside the bus station, wearing a mask. He also specially bought a pair of black sunglasses and wore a camouflage uniform bought from a hardware and labor insurance store, dressed like

She was a female worker. In order to look more like me now, Su Ziqing also bought a canvas bag. The canvas bag was specially stained with water and thrown into the soil of the flower bed. There was also a lot of soil on the canvas bag.

He could only wait outside the bus station to see if there was a chance to catch a car. Su Ziqing didn't dare to take a black car. Haigang City carried out a crackdown on black cars three times a year, and now there are basically no black cars.

Su Ziqing does not have a driver's license. If he is stopped by the traffic police while driving without a driver's license, it will mean a fine, and Su Ziqing's trajectory will be exposed.

"It's really not possible, we can only take a black car!" Su Ziqing wanted to turn off his mobile phone, but the risk would be higher, and he might even be monitored by the police.

Liang Yi called again.

Su Ziqing hesitated for a moment and answered the phone. Maybe the problem was not as serious as he thought, "Hello...Brother Liang? I was shopping alone. My phone was set to vibrate in my bag and I didn't hear it."

Su Ziqing's voice was very gentle, as usual.

Liang Yi pressed the call recording button on his mobile phone, "Su Ziqing, where are you now?"

"I'm in Haigang City, Beauty Mall. I want to buy a windbreaker. I also want to grow my hair! After this human trafficker gang butcher is caught, I will stop working in this industry if I can make some money." Su Ziqing was talking to him.

Liang Yi was playing a psychological game, and Liang Yi directly asked where he was. It seemed that the problem was serious.

"You are pretty if you have short hair, but if you have long hair it will be simply deceptive." Liang Yi said easily, "I have two questions to ask you!"

Su Ziqing chuckled and said, "I still have questions... Didn't I tell you everything that happened during the undercover period? You didn't kill anyone or violate work discipline! As far as I know, that's the case. Do you have any questions?"

"Did you kill Qin Peng?"

Liang Yi bluntly hit the snake seven inches. These seven words were like a bolt from the blue. For three seconds, Su Ziqing's mind went blank.

This also made Liang Yi wonder if there was really something wrong with Su Ziqing.

"No! I swear." Su Ziqing felt the seriousness of the problem. What she gave Liang Yi was He Shuang's DNA sample. Liang Yi called him. It must be He Shuang's DNA sample and the physical evidence from the crime scene.

The collected DNA is combined into one, highly overlapping.

That is to say.

He Shuang felt that he was very meticulous in his murder and did not leave any clues, so he asked Liang Yi to find the DNA left by He Shuang at the scene.

Liang Yi did not know that Qin Peng was killed by He Shuang. Before comparing DNA samples, Liang Yi had no idea who the murderer was.

"It's so scary..." Su Ziqing thought to himself, the DNA sample found by Liang Yi at the crime scene of Qin Peng's murder was so cool. Su Ziqing had never been to Qin Peng's house, nor was he too close to Qin Peng.

contact, what could it be?

How cool it is!

Was it He Shuang who deliberately left DNA at the scene of the murder of Qin Peng?

This is impossible...

Why does Liang Yi want her DNA sample?

"In the study where Qin Peng died, in the book, I found short red and blue hair. This short hair was very similar to your hair, so I took your DNA sample. Qin Peng had his throat cut.

I know you have practiced Sanda and are best at playing with the butterfly knife. I think Qin Peng's throat was injured by the sharp butterfly knife. There is a knife wound on your left hand. Judging from the pattern of the knife wound, it doesn't look like it at all.

The injury was caused by a kitchen knife used to cut vegetables. The forensic identification results have come out. Your DNA completely coincides with the DNA of the hair sandwiched in the book page! There are also fingerprints. Although the scene has been carefully processed, but that

A book about the study of pi still has half a fingerprint on it, and the preliminary identification of the fingerprint is more than 56% similar to the fingerprint on your right index finger."

"The DNA completely overlaps! The similarity rate of the fingerprints is also more than 50%. Do you have anything else to say? Qin Peng's death time should be between nine and twelve o'clock in the evening. You have evidence of alibi.

Is that necessary? A third person’s testimony is needed.”

Su Ziqing was helpless!

In this situation, jumping into the Yellow River can't clear him away. Even if he has evidence of alibi, DNA can identify a murderer. At the beginning, she really shouldn't be clever and provide the DNA of the real murderer, He Shuang.

.

Who could have thought of such a coincidence?

"I will go back to the Harbor City Police Station and tell you clearly in person! My phone will not be turned off. This is all a misunderstanding." Su Ziqing tried his best to calm down his emotions, finished the complete sentence, and hung up the phone in a hurry.

The whole person's soul will be hollowed out.

During the time when Qin Peng died, she had no alibi because she was also doing illegal things during that time. If she told the truth, it would be enough to go to the police station and spend three years in jail.

As for providing a fake DNA sample? That means there is no silver 300 taels here.

Su Ziqing lowered her sunglasses and had only one thought in her mind: run away!
Chapter completed!
